Method for grafting photinia davidsoniae to annatto photinia

Abstract

The invention relates to a method for grafting photinia davidsoniae to annatto photinia. The method for grafting the photinia davidsoniae to the annatto photinia comprises the following steps that stock selecting: a young photinia davidsoniae with a developed root system is selected as the stock; scion selecting: a newborn semi-lignified branch of the annatto photinia is selected as the scion; grafting preparation: grafting is conducted during January to May; grafting process comprises a transplanting process and follow-up management, transplanting is conducted on the photinia davidsoniae after being grafted, and root cutting treatment is conducted on the root of the photinia davidsoniae during transplanting; the follow-up management is that when a bud branch grows to 15 to 20 cm, a binding membrane is removed. According to the method for grafting the photinia davidsoniae to the annatto photinia, the photinia davidsoniae stock is grafted to the annatto photinia, transplanting is conducted after grafting is conducted, the root cutting treatment is conducted when transplanting is conducted, and leaves and buds on the stock are treated before or after grafting, so that the nutrition is provided for the scion fully, the growing speed of the scion is high after being grafted, and the survival rate is high.

Description

technical field [0001] The invention relates to a grafting method, in particular to a method for grafting Photinia alderwood to Photinia mahogany. Background technique [0002] Photinia is a woody plant of the genus Photinia in the family Rosaceae of the order Rosaceae. It is an evergreen tree that likes a warm and humid climate. Pruning, mainly produced in the Yangtze River Basin and areas south of the Qinling Mountains. There is also a small amount of cultivation in North China. It can be used for medicinal purposes and has great ornamental value. [0003] Photinia fraseri (scientific name: Photiniaxfraseri) is a collective name for hybrid species of Photinia in the family Rosaceae. It has bright colors and can be formed into balls, hedges and walkways. It has good landscape effects and has high economic and ornamental value. The cultivation methods of Photinia fragrans mainly include tissue culture, cuttings and grafting. Among them, tissue culture has high requirements ...

AI Technical Summary

Problems solved by technology

The cultivation methods of Photinia fragrans mainly include tissue culture, cuttings and grafting. Among them, tissue culture has high requirements on cultivation facilities, professional technical requirements and production costs, and is not suitable for large-scale promotion and use; although cuttings are simple to operate and low in cost, However, the survival rate is low and the growth is slow; the grafting method has also been studied in the cultivation of Photinia fragrans, for example, the invention patent of application number 201410347059.8 "a method for grafting and raising seedlings of Photinia small-leaf Photinia" discloses a method using large-leaf Photinia The method of grafting Photinia microphylla as rootstock can speed up the seedling cycle of Photinia microphylla while maintaining the excellent ornamental characteristics of Photinia microphylla

However, this method can only be used from late May to late June, and has high requirements for grafting time and climate, which severely limits its use effect in the actual seedling raising process

[0004] It can be seen that there are still few researches on the grafting technology of Photinia fragrans, and there is an urgent need for a grafting technology with less restrictions on seedling cultivation, simple operation and high survival rate.
